Abstract

The invention relates to the field of electroluminescence, and discloses a compound, an organic electroluminescent device and a display device. The structural formula of the compound is represented bya formula (I). The organic electroluminescent device made of a material of the compound has low driving voltage and high current efficiency, and meanwhile, a transmission layer or an injection layerof the organic electroluminescent device can be prepared by using the compound through a solution method.

Description

technical field [0001] The present application relates to the field of electroluminescence, in particular to a compound, an organic electroluminescence device and a display device. Background technique [0002] At present, organic electroluminescent (OLED) display technology has been applied in smart phones, tablet computers and other fields, and will further expand to large-size application fields such as TVs. In the development process of nearly 30 years, people have developed various OLED materials with excellent performance, and through different designs of device structures, and optimization of device life and efficiency, the commercialization process of OLEDs has been accelerated, making OLED OLEDs are widely used in display and lighting fields. [0003] However, due to the huge gap between the external quantum efficiency and internal quantum efficiency of OLEDs, the development of OLEDs is greatly restricted, and one of the most important factors is that the efficien...
